Description

Technical Field

[0001] This application relates to the field of electrical connectors, and particularly to a socket and an electronic device. Background Art

[0002] The Type-C interface is a connection standard applicable to the consumer electronics field, with high-frequency transmission and energy transmission capabilities. It supports plugging in either direction, solving the defects of the existing traditional Micro-USB interface, such as low transmission rate and non-support for plugging in either direction. Existing sockets generally include a plug-in component and a metal shell. When applied to an electronic device, there is a jack on the electronic device housing for the metal shell of the socket to enter. In waterproof design, a waterproof ring is sleeved on the outer surface of the metal shell, and waterproofing is achieved by squeezing the waterproof ring between the metal shell and the jack of the electronic device housing. At the same time, waterproof design between the metal shell and the plug-in component can achieve waterproof performance. However, when implementing this solution, since the metal shell has a certain thickness, after it is inserted into the jack of the electronic device housing, it is necessary to squeeze the waterproof ring, and the size of the jack needs to be kept large enough, which is not conducive to the ultra-thin design of the electronic device. Summary of the Invention

Waterproof glue is injected into the adhesive hole. The waterproof glue fills the gap and bonds to the inner wall surface of the adhesive hole. After the waterproof glue cures, a glue block is formed.

[0008] Preferably, the plug-in member further includes a partition formed between the first terminal group and the second terminal group.

[0010] Preferably, a glue injection port communicating with the gap is formed on the upper surface of the independent tail portion. The top wall of the adhesive hole continues to extend backward to form a covering portion covering the glue injection port. The waterproof glue is injected into the gap from the glue injection port.

[0011] Preferably, a circular groove is formed on the front end face of the main body of the fixing shell around the assembly hole. The circular groove includes an installation groove for installing a waterproof ring, an inner wall located between the assembly hole and the installation groove, and an outer wall located outside the installation groove.

[0031] The fixed housing 10 is made by powder metallurgy process or die casting process, and the preferred material is aluminum alloy. The cross-section of the fixed housing 10 is generally in a rectangular structure. The fitting hole 12 is used for inserting the plug-in part A. The fitting hole 12 includes a front hole 121, a rear hole 122 located behind the front hole 121, and an adhesive hole 123 located behind the rear hole 122. The inner diameter of the front hole 121 is smaller than that of the rear hole 122, and a holding step 125 is formed at the junction of the front hole 121 and the rear hole 122. The holding step 125 is formed on at least two opposite side walls of the fitting hole 12. For example, the lateral side walls of the front hole 121 and the lateral side walls of the rear hole 122 are flush, and the holding step 125 is only formed at the junction of the upper and lower side walls of the front hole 121 and the upper and lower side walls of the rear hole 122; or the upper and lower side walls of the front hole 121 and the upper and lower side walls of the rear hole 122 are flush, and the holding step 125 is only formed at the junction of the lateral side walls of the front hole 121 and the lateral side walls of the rear hole 122; or, the holding step 125 is formed on the entire periphery at the junction of the front hole 121 and the rear hole 122; or, the holding step 125 is formed on three side faces at the junction of the front hole 121 and the rear hole 122. The inner diameter of the adhesive hole 123 is larger than that of the rear hole 122, and a stepped surface 126 is formed at the junction of the rear hole 122 and the adhesive hole 123. The stepped surface 126 can be a vertical surface or an inclined surface. The stepped surface 126 is preferably provided on three inner wall surfaces of the fitting hole 12, and no stepped surface 126 is formed on the upper wall surface.

[0032] A plurality of positioning structures 124 are provided on the lower inner wall surface of the adhesive hole 123. The positioning structures 124 are grooves and protrusions arranged at intervals. The top wall of the adhesive hole 123 continues to extend rearward to form a covering portion 14, and the covering portion 14 extends beyond the rear end of the adhesive hole 123. The ear portions 16 extend outward from both lateral sides of the main body 11, and include a horizontal portion 161 and an insertion foot 162 extending downward from the horizontal portion 161. The rear side of the horizontal portion 161 of the ear portion 16 extends beyond the rear end of the adhesive hole 123 and does not extend beyond the covering portion 14, and a notch 15 is formed between the horizontal portion 161 and the ear portion 16.

[0033] The annular groove 13 includes a mounting groove 131 recessed backward from the front end face 17 of the main body 11, an inner wall 132 located between the mounting groove 131 and the front hole 121, and an outer wall 133 surrounding the outer periphery of the mounting groove 131. At least a part of the abutting step 125 is formed on the rear end face of the inner wall 132.

[0034] Please continue to refer to Figure 2 , Figure 3 , Figure 6 As shown, the plug-in part A includes a first terminal group 21, a second terminal group 22, a partition 23 disposed between the first terminal group 21 and the second terminal group 22 in the up and down direction, and an insulating body that holds the first terminal group 21, the second terminal group 22, and the partition 23 as a whole.

[0035] Both the first terminal group 21 and the second terminal group 22 include a plurality of independent conductive terminals. Each conductive terminal includes a contact part 211 exposed to the outside on one side, an embedded part 212 completely wrapped by the insulating body, and a welding leg 213 extending backward outside the insulating body. The partition 23 includes a plate body 231 and lateral extension parts 232 extending laterally outward from the two lateral sides of the rear end of the plate body 231. The first terminal group 21 and the second terminal group 22 sequentially include a ground terminal, a pair of signal terminals (optional), a power supply terminal, a plurality of signal terminals, a power supply terminal, a pair of signal terminals (optional), and a ground terminal in the lateral direction. The partition 23 is provided as two independent parts on the two lateral sides. The plate body 231 is located between the ground terminals of the first terminal group 21 and the second terminal group 22. There is no partition between the two power supply terminals of the first terminal group 21 and the second terminal group 22 and the plurality of signal terminals in the middle. The partition 23 may be in contact with the ground terminal or not in contact with the ground terminal.

[0036] The insulating body includes a first insulator 30 that first forms and fixes the first terminal group 21, the second terminal group 22, and the partition 23 together, and a second insulator 40 that wraps at least a part of the first insulator 30. The first insulator 30 includes a clamping portion 31 inserted into the front hole 121 of the assembly hole 12, a pre-fixing portion 33 that extends forward from the clamping portion 31 and holds the contact portions 22 of the first terminal group 21 and the second terminal group 22 and the partition 23 as an integral body, a limiting portion 32 formed at the rear end of the clamping portion 31, and an independent tail portion 34 located at the rear end of the limiting portion 32 and separated from the limiting portion 32. A gap 35 is formed between the independent tail portion 34 and the limiting portion 32, and they are connected together only through the first terminal group 21, the second terminal group 22, and the partition. When the first insulator 30 is injection-molded, a plurality of material tapes are connected to the front and rear of the first terminal group 21, the second terminal group 22, and the partition 23. After the first insulator 30 is injection-molded, some of the material tapes need to be cut off. The material tapes at the front ends of the first and second terminal groups 21, 22 need to be cut off so that the front ends of the first and second terminal groups 21, 22 are exposed to the outside, and the second insulator 40 is required to cover them. The lateral extension portion 232 of the partition 23 extends out of the outside of the first insulator 30 in the lateral direction. A glue injection port 341 communicating with the gap 35 is provided on the upper side of the independent tail portion 34, and the glue injection port 341 extends in the front-rear direction and is open on the upper side.

[0037] The second insulator 40 includes another clamping portion 41 located on the front side of the clamping portion 31 of the first insulator 30, a transition portion 42 extending forward from the clamping portion 41, a wrapping portion 43 extending forward from the transition portion 42, and an embedded tail portion 44 partially filling the independent tail portion 34 of the first insulator 30. The outer diameter of the clamping portion 31 of the first insulator 30 is the same as the outer diameter of the clamping portion 41 of the second insulator 40 and is located in the front-rear direction. The outer surfaces of the clamping portions 31, 41 are provided with limiting ridges 311, 411, and the outer diameters of the clamping portions 31, 41 are smaller than the outer diameter of the limiting portion 32. The outer diameter of the clamping portions 31, 41 is larger than the outer diameter of the transition portion 42. The second insulator 40 wraps and protects the front edges of the contact portions 211 of the first and second terminal groups 21, 22 and fills the remaining places that need to be filled at the same time.

[0038] The clamping portions 31 and 41 of the first insulator 30 and the second insulator 40 are combined into a clamping portion, and the clamping portions 31 and 41 fix the sleeve to be sleeved and fixed in the front hole 121 of the assembly hole 12 of the fixed shell 10. In an embodiment, the outer diameter of the clamping portion 31 of the first insulator 30 is smaller than the outer diameter of the clamping portion 41 of the second insulator 40, and the clamping portion 41 of the second insulator 40 wraps the clamping portion of the first insulator 30 on the outer layer to achieve better bonding. In an embodiment, the first insulator 30 does not have the clamping portion 31, and the clamping portion is formed by the second insulator 40, but the clamping portion 41 is wrapped outside the first insulator 30.

[0039] For key reference Figure 3 、 Figure 5 、 Figure 6 As shown, the plug-in part A of the socket of the present application is inserted into the assembly hole 12 of the fixed shell 10 from back to front. At this time, at least part of the clamping portion 41 of the second insulator 40 is clamped between the inner wall surfaces of the front hole 121, and the clamping portion 31 of the first insulator 30 is also clamped and fixed by the inner wall surface of the front hole 121. The limiting end surface 321 of the limiting portion 32 of the insulating body abuts against the abutting step 125 at the junction of the front hole 121 and the rear hole 122 to limit the further forward movement of the plug-in part A, and the limiting portion 32 is fixed between the inner wall surfaces of the rear hole 122. The gap 35 is located in the bonding hole 123 at the rear side of the rear hole 122. The covering portion 14 covers the upper side of the glue injection port 341 to close the open side of the glue injection port 341. Glue is injected into the gap 35 from the glue injection port 341. The glue adheres to the conductive terminals, the partition plate 23 and the inner wall surface of the bonding hole 123 in the gap 35. At the same time, the stepped surface 126 is adhered by the glue, and after the glue is cured, the glue block 50 is formed, and the glue block 50 realizes the sealing of the front and rear sides. The partition plate 23 protrudes laterally from the independent tail portion 34 of the first insulator 30. The lateral extension portion 232 extends from the notch 15 between the covering portion 14 and the ear portion 16 to one side surface of the ear portion 16. The lateral extension portion 232 and the ear portion 16 are fixed together by spot welding. In this way, the plug-in part A is fixed in the fixed shell 10 to prevent it from withdrawing.

[0040] The insulating body is a combination of the first insulator 30 and the second insulator 40. The insulating body includes a clamping part formed by the common combination of the clamping parts 31 and 41, a transition part 42 extending forward, and a docking tongue part formed by the wrapping part 43 being combined outside the pre-fixing part 33. The insulating body is fixed in the fixed shell 10. The docking tongue part needs to bear a large insertion and extraction force. The second insulator 40 is provided with a clamping part 41 clamped in the assembly hole 12 of the fixed shell 10, which can effectively increase the strength of the docking tongue part. The contact parts 21 of the first terminal group 21 and the second terminal group 22 are respectively exposed on the upper and lower surfaces of the docking tongue part.

[0041] Please refer to Figures 7 to 9 As described above, the present application further includes an electronic device, which includes a device housing 70 formed with an insertion hole therethrough, a circuit board, and the aforementioned socket. The socket is welded to the circuit board and partially inserted into the insertion hole 72. Specifically, the transition part 42 and the docking tongue part of the socket are completely exposed on the front side of the fixed shell 10 and inserted into the device housing 70 of an electronic device. The device housing 70 can be a mobile phone outer frame or the like. The device housing 70 includes a housing 71 and an insertion hole 72 penetrating the housing 71. A crimping end face 73 is formed on the rear end face of the insertion hole 72. The crimping end face 73 can be a flat surface or provided with a groove 731.

[0042] The socket is inserted into the insertion hole 72 of the device housing 70 from the rear to the front. Among them, the docking tongue part and the transition part 42 are located in the insertion hole 72. The fixed shell 10 is waterproofed by being crimped on the crimping end face 73 on the peripheral edge of the rear side of the insertion hole 72 through the waterproof ring 60. Designed in this way, it is possible to avoid inserting the metal shell of the socket into the insertion hole 72 of the device housing 70, directly using the device housing 70 as the protective shell of the docking tongue part, and at the same time performing waterproofing in a longitudinal crimping manner, effectively reducing the product size.

[0043] The waterproof ring 60 includes an insertion part 61 inserted into the installation groove 131 of the fixed shell 10 and an exposed part 62 integrated with the insertion part 61 and located outside the installation groove 131. The exposed part 62 includes an outer wrapping part 63 covering the front end face of the outer wall 133 of the annular groove 13 and a crimping end 64 located at the forefront of the exposed part 62 for crimping the crimping end face 73 of the device housing 70. The thickness of the crimping end 64 is less than the thickness of the exposed part 63. When a groove 74 is provided on the crimping end face 73, the crimping end 64 is pressed into the groove 74 for waterproofing.

[0044] In the socket of the present application, by providing a fixing shell 10 that does not wrap the docking tongue portion, the docking tongue portion is directly surrounded and protected by the insertion hole 72 of the device shell 70 of the electronic device. At the same time, by providing an annular groove 13 on the front end face 17 of the fixing shell 10 to accommodate the waterproof ring 60, the waterproof ring 60 is longitudinally crimped on the crimping end face 73 after the insertion hole 72 of the device shell 70 to achieve waterproofing, and the size of the socket is minimized.

[0045] In the socket of the present application, the second insulator 40 is provided with a clamping portion 41 that is at least partially clamped in the assembly hole 12 of the fixing shell 10, so that the plastic at the docking tongue portion is supported by the fixing shell 10 and will not be easily broken or cracked.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0047] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
